Kuchisake-onna: The Slit-Mouthed Woman Who Panicked 1979 Japan

A woman in a cloth face mask turns up in Studio Ghibli’s Pom Poko (1994), in the 2007 horror film Carved, and, decades later, in the video game Ghostwire: Tokyo. In every version the routine is the same: she stops someone and asks whether she is pretty. Before any of that, at the end of 1978, she was simply a rumour passing between children in Gifu Prefecture, and within weeks a local newspaper had printed her.

Quick facts

• Verdict: Not a documented incident and not an old temple-record monster — Kuchisake-onna is a school-born urban legend that started as word-of-mouth rumour in Gifu Prefecture in late 1978 and was amplified into a national story by newspapers and magazines.
• Name: Kuchisake-onna (口裂け女), literally “slit-mouthed woman.”
• Type: Modern urban legend, spread through school oral culture and the press rather than online.
• Earliest known record: 26 January 1979, a page-one column in the Gifu Nichinichi Shimbun, checked on microfilm by the National Diet Library.
• Where it spread: From Gifu Prefecture across almost the whole country by June 1979.

What the story says

A young woman stands on a street, her mouth completely hidden behind a mask. She asks a passer-by whether she is pretty. If the answer is yes, she pulls the mask away to show a mouth split open as far as her ears and asks again; if the answer is no, she attacks with a knife or a pair of scissors. That question-and-answer structure — a query, a response, a reaction keyed to the response — is the fixed skeleton of the legend, and everything else moves around it.

The details of her appearance drift from telling to telling. The usual description gives her long black hair, pale skin and white hands, a height of roughly 175 to 180 centimetres in most accounts and 243.84 centimetres in one outlier, and a blade carried out of sight. Japanese accounts record regional wardrobes: in some places she wears red clothing with a beret and high heels, in others a kimono and sunglasses. Countermeasures circulated alongside her. Children traded the idea that bekko candy, a hard amber sweet, or the word for hair pomade would make her falter long enough to get away — small, oddly domestic pieces of defensive lore attached to an otherwise open-ended threat.

Earliest known record

One account places the start of the rumour in Gifu Prefecture in early December 1978, while others say only the end of that year, and its first appearance in the mass media is a report in the Gifu Nichinichi Shimbun on 26 January 1979. That newspaper date is the earliest fixed point anyone can put a finger on. No account fixes the exact day, and accounts differ even on the month, and the gap between the first playground retelling and the first printed one is not documented, so there is no way to say who told it first or where exactly they were standing.

The newspaper date is not just repeated from one reference work to the next. In a published reference answer, the National Diet Library reports checking the Gifu Nichinichi Shimbun on microfilm (call number YB-255) and finding the item on page one of the morning edition of 26 January 1979, in a column headed “Henshu Yoki”. The same answer says that the issues from 23 to 29 January were also searched and no other matching article turned up. That makes the January date a checked record rather than a received one, and it also shows the form of the first appearance: an item in a named front-page column.

Other accounts agree on the broad shape: the modern story originates at the end of 1978, and Gifu Prefecture is named as the place it came from, though they add that versions differ. One account goes further and traces the first rumour to a woman on a farm in a town in Gifu Prefecture, who said she had seen a woman with a mouth split to the ears standing in a corner of the garden. The same account flags that other versions exist, so this is one candidate starting point, not a settled one. Anything earlier than 1978 belongs to the origin theories discussed below, not to the record.

What is documented

What can be stated with confidence is the scale and the speed. Press coverage turned a local rumour into a nationwide alarm: newspapers and magazines carried the story, panic followed, and children started walking to and from school in groups rather than alone, while teachers and parents organised patrols. That detail is the most concrete trace the legend left on ordinary life — an adjustment in daily routine, made by families reacting to something that had never been verified.

The spread is also documented in outline. From Gifu the story reached nearly the whole country by June 1979, and one account records it dying away quickly once the summer holidays began in August. The mechanism is worth noting: this is a pre-internet legend, carried by schoolchildren talking to each other and by reporters writing it up, which is why the school calendar shows up in its life cycle at all.

The folklorist Yoshiyuki Iikura describes Kuchisake-onna as probably the first home-grown Japanese “urban legend”. He links the speed of the spread to a change in children’s lives: more of them were attending cram schools, which drew pupils from several school districts, and before that a rumour rarely crossed district lines. On this reading the legend’s reach depended on a new kind of social network, not only on the press.

The local paper also recorded the end of the episode in Gifu. According to a reference answer in the National Diet Library’s Collaborative Reference Database, the Gifu Nichinichi Shimbun’s evening edition of 15 June 1979 ran an article with an imagined picture of the woman, headlined to the effect that the Kuchisake-onna born in Gifu was finally dying down. A local newspaper index had listed it under 16 June until a check of the page corrected the date. A local history published by the Gifu Shimbun company in 2000 later gave her an entry, which shows the episode being kept as part of the prefecture’s own record.

The candy motif left a small documented footprint of its own. The PC game Heiankyo Alien adopted candy as an item for driving off enemies, taking a piece of playground defensive lore and turning it into a game mechanic.

What is contested

Almost everything about where she came from. The sources list explanations rather than settling on one. Japanese accounts include a vengeful spirit connected to a victim of the Gujo uprising, a supposed true incident in the Meiji era, a person who had escaped confinement, a cosmetic surgery that went wrong, and the ghost of a bus that went into the Hida River. English-language accounts add an attack by a jealous woman and a dental procedure that went wrong, and note a Western retelling in which a samurai’s unfaithful wife or mistress had her mouth cut as retaliation. None of these is presented as the established source of the 1978 rumour. They are better read as explanations invented after the fact, each one reverse-engineering a backstory for a figure who arrived without one.

The timing of the peak is also described differently depending on where you look. One account says the story became popular in the summer of 1979; another has it already nationwide by June and fading fast from August; and in Gifu itself the local evening paper was calling the fuss finally dying down by mid-June. Her physical description is inconsistent in the same way, with the 243.84-centimetre figure sitting far outside the ordinary range given alongside it.

What the sources add

The newspaper and library records sharpen the timeline more than they change it. The 26 January 1979 date has been checked against the microfilm of the Gifu Nichinichi Shimbun, and the item turns out to sit in a named column on page one of the morning edition. A search of the surrounding week found nothing else, so there is no sign of an earlier report in the same paper that week. None of these records fixes the day the rumour started; late 1978 remains the limit of what can be said.

The records also show that the legend ran on a local clock and a national clock. The Gifu paper was reporting the fuss as dying down on 15 June 1979, around the time another account describes the story as reaching almost the whole country and before the August summer holidays that are said to have ended it nationally. The place where the rumour started seems to have moved on first.

On origins, the newer material adds candidates rather than answers. One account names a town in Gifu Prefecture and a woman on a farm, while marking this as one version among several; others simply say Gifu, late 1978. None of these sources ties the first rumour to a named person or to a confirmed event.

What survives is a local memory. A folklorist calls Kuchisake-onna probably the first home-grown Japanese urban legend. A 2000 local history published by the Gifu newspaper company gave her an entry. That is how a playground rumour ended up in the region’s own account of its past.

Adaptations

The entry points most readers outside Japan meet first are all fiction, and all much later than the rumour. Studio Ghibli’s animated film Pom Poko (1994) features her; the live-action horror film Carved (2007) and Kuchisake-onna Returns (2012) both build on her; and the video game Ghostwire: Tokyo includes her among its figures. None of these is evidence about the 1978 events — they are how a schoolyard rumour became a durable character. The trail runs the other way round from what the films suggest: the panic came first, the adaptations followed.
